It's a slippery slope though. We saw this with Google, so it's not like it's a straw man. First it's small, discrete ads to the side. Then it's the first few entries are ads, but are marked as such. Then it's the first page of entries. Then the marking disappears. (Yeah, they put it back eventually after a backlash. I wouldn't expect a company like Brave to do the same, though.)

I just go with a search engine I pay for that doesn't offer any ad-supported stuff (kagi.com). That way, I'm directly supporting the service, and they have zero incentive to start showing me stuff that other people are paying for me to see and which I definitely don't want to see.
